A PARADOX
"For every action there is an opposite and equal reaction."
Sir Isaac Newton, 1687
The voice is no exception. The ACTION [breath] STAYS down; the REACTION {sound} GOES high. The sound is high, the breath remains low and MOVING. This coordination allows the sound to vibrate freely in the windpipe. Squillo is the result.
A man jumped out of a 10 story building. On the fifth floor he stated, "So far so good." It was only after he hit the ground that he made any sound. SPLAT!
When the breath stays low, the sound flies high.
